Run the 2022.2.2 installer and see if that corrects the issue.

Bingo . sorted!
Many thanks for the quick reply ( I left an extra backup running and went to bed - hence the delay ).

This saved me from needing to call upon an OS restore !

Similar issue after upgrading from 2022.1 to 2022.2. As suggested, running the installer a second time cleared up the web server failure to start problem..
